ProScan 1.5 adds a new "Shuffle" feature

 

With this button your users can move a page of the TIFF file forward or backwards in the file.

 

 

When they click the Shuffle icon they will see a popup menu:

 

 

The current page displayed will be moved forward or backwards in the file based on their selection.

 

The template is aware of the start and end of the file and has its own error checking and handling.

 

 

File Compressions

Since it is currently impossible for ProScan to know what compression or DPI setting was used on each page when a TIFF is loaded from the disk, ProScan is set to use these default values:

 

TIFCompression        IECA:LZW (value of 2)

DPI                        200 DPI

 

The LZW compression is a moderate compression that allows color images to be saved.

The 200 DPI setting will produce decent print quality images.

 

Hint: You can use a setting like GROUP4 to get a smaller size, but a color image will be rendered as B&W when the page is shuffled!

 

 

If you want to change these in your application, it is not necessary to modify the PS_ProScan.ccl file.

 

The default values are stored as:

 

ShuffleCompression

ShuffleDPI

 

To set your own values, just use these commands to save them with the other ProScan settings:

 

!Update Shuffle Data defaults

RIC.PutData( 'Proscan', 'ShuffleCompression', ,ShuffleCompression,  )

RIC.PutData( 'Proscan', 'ShuffleDPI', , ShuffleDPI',  )

 

 

** Where ShuffleCompression is one of the ImageEx valid compressions (see TIFFCompression in this file)

** Where ShuffleDPI is a valid DPI setting

 

These values will be loaded at the start of the procedure (along with the others).

 

If you do not set your own values - the defaults above will be used.
